Hi, because of horror stories in this bulletion board I disconnected my Vro pump,plugged the oil line, drained my tank and am running 50 to 1 premix .I had two wires going to the oil pump from the engine,one was black to ground, the other was tan .I disconnected the tan and taped also the wire going to ground. Going fishing tonite, the no oil horn came on. Did I disconnect the wrong wires? Any ideas?
